MAP HOLDER.

Application filed September This invention relates to holders foruse in the operation of strip maps contemplating the provision of a housing having manually and simultaneously operable spools therein for traveling appropriate portions thereof over a bridge plate positioned immediately behind a sight opening provided in the'l'ace of the housing to permit reading of the exposed portions of the map. I

With the above and other objects in view the invention further includes the following novel features and details of construction to be hereinafter more fully described, illustrated in the accompanying drawing and pointed out in the appended claims.

Inthe drawing:

Figure 1 is a perspective view of the invention;

Figure 2 is a vertical view thereof;

Figure 3 is a transverse section taken through one of the spools and illustrating the construction thereof.

Figure 4 is a diagrammatic plan View of a spool and tab end of the strip map.

Figure 5 is a horizontal. section taken through a spool and illustrating the manner by means of which the tab end of the strip map is securely held thereon.

' cover plate 11.

Referring to the drawing in detail wherein like characters of reference denote respective parts, the reference character 10 indicates the back of a housing having the forward portion of the housing consisting of a cover plate 11 hingedly scci'lred upon its lower edge while their res wctive and opposite ends are being held against accidental displacement by an off set spring lii'iger '11 arranged upon the inner side of the back plate 10 and having its free end crimpcd or bent upon itself-and fit- .ted within a. depressed portion arranged upon the inner side and adjacent the top of the A relative large sight opcning 12 being provided within the face of the cover plate 11 and immediately behind the same and in slight spaced relation thereto is a bridge plate 3 having its respective end portions rolled as indicated at 14:, the purpose of which will be readily apparent.

Cross section rectangular shaped sleeve men'ibcrs 15, of which may be properly termed spools, receive axles or shafts 16 therein for journaling the same within the opposite side walls of the cover plate 11 and provided with knobs or dials 17 upon their corresponding ends in order that the spools may be imparted a rotary movement upon 7 the simultaneous upon the strip being so arranged 1, 1926. Serial No..133,044.

r operation of the knobs 17. lhe axles 16 having reduced portions 18 provided at intermediate points in their lengths and within which are received and tensioned the ends of spring lingers 19 struck from the sleeves or spools 15. A strip map such as indicated at 21. having appropriate portions thereof wrapped upon the spools or sleeves 16 and adapted to expose appropriate portions of its length to the sight opening 12 and upon the face of the bridge plate 13, in themanner as illustrated in Figure 2 of the drawing. The opposite end portions of the strip ma 20 are provided with tabs 21 fittedwithin e ongated slots in the sleeves or spools 15 beneath the axle 16 and held against'displacement by the spring fingers 19 carried by the sleeve.

It will be noted from the foregoing description and accompanying drawing that; the invention provides an exceedingly useful and advantageous. stripmap holder which owing to the provision of a securing hook or clamp 23' provided upon the rear side of the plate 10 which may be fitted upon an appropriate portion of a motor vehicle within convenient reach of the operator in order that portions of the map may be read, the knobs l7 rotated an appreciable distance to expose other portions of the map. The map as to provide ample and sullicient. space upon the opposite. sides thereof to permit the ottin g down of ex )enditures distances, upon the strip and which may be readily added to ascertain the entire course or expenditure of the trip as a Whole or between certain The invention is susceptible of various changes in its form provisions and minor details, of construction, and the right is here.- in reserved to make such changes which properly fall within the scope of the appended claims.

Having thus described my invention what is claiu'led is 1. A map' holder comprising a housing having a sight opening in the face thereof, spools of substantial rectangular cross section having spring fingers struck therefrom at appropriate points int-heir lengths, axles extended within the spools and provided with reducedportions at appropriate points in their lengths and within which are tensioned the free ends of the spring fingers, said spools having slotted portions, and a strip map having tab portions received within the slots in the walls of the spools and upon designated points.

which is tensionedthe opposite sides of the axles to retain the map against accidental displacement within the housing.

2. In a map holder, a housing having a strip map movable therein and a winding spool to receive the strip, said spool comprisin a hollow shank and having an operating nob thereon, an annular groove within the axle, and as ring finger carried by the shank and extent ed Within the groove to provide an interlocking connection between the shank and axle.

3.-In a map holder, a housing having a 'ing upon the strip,

strip map movable therein and a winding spool to receive the strip, said spool comprising a hollow shank having oppositely located slots to receive one end of the strip, an axle extending through the shank and bearand means adapted to provide an interlocking connection between the axle and shank-to clamp the strip between the axle and shank to hold the strip in position.

In testimony whereof I ailix my signature.
